About 20 years ago I was with my old man in the Grampians for a week and he (being of the scientific mind) was determined to decipher which available firewood, at the campsite we'd used for yonks, was the best, as in heat and how long it burnt.
We had redgum, yellow box, swamp gum, native cherry and black wattle available dry in profusion.
Over the week we burnt various combinations and permutations of available wood and the clear winner was black wattle on its own.
The temp test was how fast a really cranking fire could melt a beer bottle. Black wattle burnt white hot on it's own. Was ok in combination with redgum, but not as hot.
Black wattle has to be used carefully in a coonara........... been known to melt them if used wrongly around here.
